PAGE 1 110Kv power supply system relay protection function brief analysis Not only the 110Kv power supply system relay protection function brief analysis electrical power system security and the reliability relate electrical power system itself the movement, similarly relates in the power transmission scope the factories and mines, the enterprise, whether the inhabitant uses electricity normally.Because simultaneously the electrical power system has the strong connectivity, electrical power system interior any barrier all possibly affects the overall system normal operation, thus we must complete the power supply system practically the relay protection question. First, the 11OKV power supply system Generally speaking electrical power system including the electricity generation, changes the electricity, the electric transmission, the power distribution and uses electricity and so on five links, between five links restricted mutually, cooperates mutually has facilitated the electrical power system stability together.But in fact, because these five links not always in the identical place, the identical time complete, the electric transmission must surmount the vast area, simultaneously the electrical power system must not carry on the connection with the equipment, thus strengthened its movement environment complexity, causes electrical power system the zero failure rate to guarantee with difficulty.The 110Kv power supply system is in the entire electrical power system important constituent, it whether safe, stable, reliable movement, not only relates the system own movement quality, whether moreover relates in its power transmission scope general user normal prompt using electricity, it the economical normal development and the society is stably taking on the important energy safeguard duty to the power transmission scope in.Therefore the 110KV power supply system design and the movement management must observe national comprehensively the related standard and the
